Question

That is a large square portrait of a leader that covers an area of 4489 cm×2.lf each side has a 2 cm liner , what would be it's area ?

Answer 1

Area of the liner will be 520 cm²

Step-by-step explanation:

A large square portrait of a leader covers an area = 4489 cm²

Let the length of the sides of the portrait = x cm

then area of the portrait = x²

now x² = 4489

x = 67 cm

If each side has a liner of 2 cm then the inner sides of the portrait will be = (x - 4) cm

= (67 - 4)

= 63 cm

Now the area of the inner square = 63 × 63 = 3969 cm²

Now the area of the liner = 4489 - 3969 = 520 cm²

Therefore, area of the liner will be 520 cm²
